METHOD OF MAKING SIHIMS.

Application filed March 19, 1928. Serial No. 625,960.

This invention relates to an improved and therefore does not interfere with the 55 method of making shims and in particular operation of the press head 7 to shims which are used between the parts In order to bind theilaminae 6 of the shim of a bearing and which can be reduced in together,I provide the press head onits sides thickness without any inconvenience or a with downwardly extending projections 10,

' loosening of the. other laminae which form the the inner lower edges of which are bevelled 60 shim. as at 11. The distance or width of the head A particular object therefore is to produce between these projections is slightly less than a shim which can readily be reduced in thickthe width of the shim, so that the projecness, which will act. as a take up for wear tions, when the head is moved downwardly,

on the shaft and prevent rattling of the bearwill bend the edges of the laminae downward- 65 mg parts and which can be manufactured ly, the latter projecting over the sides of the economically and efficiently.v press bed sufficiently to allow this.

A further object of my lnvention is to pro- When the press head has reached thelimit duce a shim, the laminae of which will hold of its travel, thelaminae 6 have not only been themselves together without the aid ofa bindcompressed but while under compression the 70 ing element such as lead or other malleable ends will have been bent down as at 12 so metal. 7 that the edges of each lamina overlap the Referring to the drawings wherein one emedges of the lamina directly beneath 1t, in

Figure 1 is a top plan view of'a shim comtogether due to the adhesion of the metal and posed of thin sheets of metal such as brass crowding together of the ends into a mass, assembled on the bed of a power press, the the metal of the shims being malleable and pressure exerting head of the press being therefore susceptible to such chan e under the extreme pressure exerted by t e press Figure 2 is a front elevation of the power head. a
